Hub. Australia. 



I have uot seen this species, which belongs to the same 

 group as fiaviventris, Sm., but may be distinguished from all 

 other Australian species by the serration of the anterior 

 femora. No definite locality is known.

This species, of which I have not seen specimens, is very 

 near fiaviventris, Sm., from which it may be distinguished 

 by the interrupted bands on the apical dorsal segments, 

 which are continuous in that species. There is no mention 

 in Handlirscli's description of any abnormal structure of the 

 apical joint of the intermediate tarsus, which in fiaviventris 

 is very long and slender at the base. Handlirsch, in his 

 key, refers under calcarina to his figure of an intermediate 

 metatarsus which, according to the plate and description, 

 belongs to egens. This is evidently a slip, the only one I have 

 yet found in the work of that author.

This is very near calcarina, Handl., which may prove to 

 be a synonym or subspecies. I have not taken the species 

 myself.

The male is easily distinguished from flavifrons by the 

 normal clypeus and labium and by the fewer spines on the 

 basal joint of the fore tarsus. It is nearer in structure to
